Tibco Integration with MS CRM

Hi,
I am getting an exception "Credentials cannot be used for NTLM authentication" when trying to invoke the CRM webservice from Tibco and came to know that there is a proxy for authenticating it. Can anyone provide some details on this?

Another is to install a proxy (e.g. ntlmaps-0.9.9.0.1) whose job is to take the request and re-route the same using NTLM authentication to MSCRM.
Basically, you give the usual MSCRM URL for web service but configure the HTTP proxy (Transport Details tab of the SOAP Request Reply activity) to point to the proxy you've installed, so that it internally redirects your requests to MSCRM server using NTLM authentication, and whatever response getting back from MSCRM is sent back to BW.

Hi Briac,
Thanks for the useful information . We were able to connect to invoke MS CRM service ( Tibco 5.6 ) when we are connecting it from Windows server 2003 but it fails from Windows server 2008 R2. After some research I found that there is some issue with NTLM authentication in 2008 R2 and I tried changing the Network Security Settings in my Local Policies.

So my question is installation of proxy required for Tibco5.6 or we can do it by changing the Network Security Settings (or both required for enabling NTLM in 2008 R2)
